FIELD OF THE DISCLOSURE

The present disclosure relates to a waterproof electronic device and a fan device thereof, and more particularly to an electronic device having waterproof and dustproof functions, and a fan device installed in the electronic device.

BACKGROUND OF THE DISCLOSURE

An industrial computer (or referred to as a rugged laptop) is usually used outdoors. Since an environment in which the industrial computer is used is generally poor, the industrial computer is required to have high-temperature resistant, low-temperature resistant, heat-dissipating, dustproof, and waterproof properties. In order for the industrial computer to have a high heat-dissipating effect, like traditional desktop computers or laptops, a heat-dissipating fan and heat-dissipating holes are preferably provided on components that radiate a large amount of heat (e.g., a central processing unit, a hard disk, or a memory). However, due to the poor environment, such a heat-dissipating approach may not achieve the goals of being dustproof and waterproof. On the other hand, a dustproof and waterproof structure may cause inconveniences in dismount and maintenance of the heat-dissipating fan.

Therefore, how to enhance maintenance conveniences and waterproof and dustproof effects of a waterproof electronic device and a fan device thereof through an improvement in structural design, so as to overcome the above-mentioned deficiencies, has become one of the important issues to be solved in this industry.

SUMMARY OF THE DISCLOSURE

In response to the above-referenced technical inadequacies, the present disclosure provides a waterproof electronic device and a fan device thereof.

In order to solve the above-mentioned problems, one of the technical aspects adopted by the present disclosure is to provide a waterproof electronic device, which includes a housing, a system component region, a waterproof wall, and a fan device. The system component region includes a first connecting device exposed to the housing. The waterproof wall is disposed between the housing and the system component region. A fan receiving area, a wire passing area and an opening exposed to the housing are defined by the waterproof wall. The wire passing area is arranged between the fan receiving area and the opening, and the opening is corresponded in position to the first connecting device. The fan device includes a fan lid, a fan body, a cable and a second connecting device. The fan lid is fixed to the waterproof wall, covers the fan receiving area, and extends to the opening. The fan body is disposed in the fan receiving area. The cable is connected to the fan body and the second connecting device, and passes through the wire passing area, and the second connecting device is coupled to the first connecting device.

In order to solve the above-mentioned problems, another one of the technical aspects adopted by the present disclosure is to provide a fan device. The fan device includes a fan lid, a fan body, a cable, and a fan-end connecting device. The fan body is fixed to one end of the fan lid. The fan-end connecting device is disposed at another end of the fan lid. The cable is connected to the fan body and the fan-end connecting device.

Therefore, in the waterproof electronic device and the fan device thereof provided by the present disclosure, the fan device provides the fan-end connecting device (or referred to as the second connecting device) that is pluggable. The second connecting device is connected to the first connecting device in a pluggable manner, so that the fan device can be disposed in a replaceable manner in the waterproof electronic device.

In addition, by virtue of “a waterproof wall being disposed between the housing and the system component region,” “a fan receiving area, a wire passing area, and an opening exposed to the housing being defined by the waterproof wall,” and “wherein the cable is connected to the fan body and the second connecting device and passing through the wire passing area, and the second connecting device is coupled to the first connecting device,” a waterproof performance of the waterproof electronic device can be enhanced.

These and other aspects of the present disclosure will become apparent from the following description of the embodiment taken in conjunction with the following drawings and their captions, although variations and modifications therein may be affected without departing from the spirit and scope of the novel concepts of the disclosure.
